Awesome idea - well suited to the lyrics and the challenge! The photo in the bubble is perfect for what you're trying to convey - combined with the couple on the couch, the message is one of sweetness and devotion - at least to me.
I like the concept. I think it might have been better to have cropped the left side where the line in the back is at(distracting)and softened the edges of the dream picture by cuttin off the white around the figures and rounding the corners. Photo quality is excellent.
This is a great take on the challenge. I have a little problem with the technique of the "dream" I'm not sure I could do better but I know it could be done better. Anyway big points for originality!
